DRAFT-HOOK.

SPECIFICATION forming part of Letters Patent No. 661,069, dated November6, 1900. Application filed January 24. 1900. Serial No. 2,685. (NomodeL) To a/ZZ whom, it may concern Be it known thatl, FRED FoLKENORDEN, a citizen of the United States, residing at New York,(Brooklyn,) in the county of Kings and JState ofNew York, have inventedcertain new and useful Improvements in Draft-Hooks; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to improvements in draft-hooks; and it consists incertain novel constructions, combinations, and arrangements of parts, aswill be hereinafter fully described and claimed.

In the accompanying drawings, Figure 1 represents a side elevation of adraft-hook constructed in accordance with myinvention. Fig. 2 representsa similar view of the said hook, but showing its jaws separated. Fig. 3is an edge view of the same, and Fig. lt-represents a side elevation ofa modified form of the said hook. Fig. 5 represents a detail viewshowing a shouldered joint between the guard-finger and the hook.

Myinvention is designed to provide hooks for tackle or hoistingapparatus of any kind, as well as for any other draft mechanism, whichshall be so formed as not to easily catch in ropes or other kinds ofapparatus located near the hooks when in use. It is designed to supplyhooks which shall be closed by a weight placed upon them and yet willhave their jaws so disposed with relation to one another as tostrengthen each other.

With these objects in view my invention comprises a draft-hook 1, formedof an attaching member 2 and a hook member 3. The attaching portion 2 isformed with an eye, as 4, which may be secured to any drafttackle. Thelower end of the attaching member 2 is prolonged to form a jaw orguardfinger, as 5. The hook member 3 is preferably reduced at its upperend, asat 6, and adapted to extend into a slot, as at 7, formed in theattaching member 2. A pivotloolt, as 8, is passed through the attachingmember and the hook member, so as to pivotally secure the two partstogether. The

hook member extends downwardly from its pivotal point in such a manneras to form a very strong hook, as 9, its outer free end being adapted tocome in contact with the jaw or guard-finger 5 when thehook is closed.

The parts of my improved draft-hook are preferably well rounded and areof such a shape, as will be seen by the drawings, that there are noprojections to engage ropes or other tackle which may be. in close moreimity to the hook. This is an important feature of my invention,especially when such hook is used in connection with shiptackle, as thecordage and other parts of the ships tackle are often closelyinterwoven, and when a hoisting apparatus is employed among them arelikely to catch upon the same, especially if there are any projectionsor shoulders upon the hooks or blocks.

Another important feature of my invention is the manner in which thejaws of the draft-hook fit upon each other. It will be seen that the endof the hook 9 comes within the inner surface of the guard-finger 5 andthat when weight is applied upon the hook it will force the hook tightlyagainst the said finger 5. It is apparent that there will be a tendencywhen a strong draft or load is applied upon the hook to straightenoutthe material forming the hook. This tendency is obviated in a largemeasure by the guardfinger 5, which so far overlaps the end of the hook9 that it gives itlateral support and prevents to a considerable degreeanychance of straightening the hook out under a severe test. Of coursethe greater the strain upon the draft-hook, the pull being applied'uponthe eye 4 and the hook 9, the more will the hook he sustained by thepressure of the guard-finger 5 against the end of thesaid hook.

To further strengthen the action of the hook member, the reduced endportion thereof,

which is passed through the slot in the attaching member, may be headed,as at'12, after the parts have been pivoted together. This head when thehook is closed will serve to strengthen the parts and limit theirmovement.

It will be noted that the joint between the two members of the hook maybe made in Various ways without departing in the least from the spiritof my invention. As seen in Fig. 4 of the drawings, the hook member maybe bifurcated at its upper end 10, the said bifurcated portion beingadapted to embrace the reduced portion 11 upon the attaching member. Inthis construction all shoulders or projections which are likely to catchin anything when the hook is in use can be dispensed with, making thehook valuable for all kinds of work.

In order to make the engagement between the guard-finger and the hookmore secure, the said guard-finger may be provided with a shoulderedportion 14-, as will clearly appear by reference to Fig. 5 in thedrawings. VVhen the parts are closed, it will be seen that the hook isstrongly supported by this kind of a joint.

It will be observed from the above description that I am enabled toproduce a draftbook which is exceedingly strong and which will not catchupon other materials when in use and which has its parts so arranged asto thoroughly brace each other. Such a hook is not complicated, butsimple of construction and easily manufactured.

Having now described my invention, what Iclaim as new, and desire tosecure by Letters Patent, is

l. A draft-hook, comprising an attaching mem ber,and a hook memberpivoted together, a guard-finger upon the attaching member extendingoutside the end of the hook for giving it lateral support, the hookbeing so pivoted that weight placed upon it will force it against theguard-finger, substantially as described.

E3. A draft-hook, com n'ising an attaching member provided with asecuring-eye,a guardfinger formed upon the attaching member, a hookmember pivoted to the attaching member and having its end restingnormally against the inner surface of the guard-finger, the pivot-pointof said hook member being arranged a little to one side of the line ofdraft on the book, so that a strain upon the hook will press it againstthe guard-finger, the said guard-finger thus giving it lateral support,substantially as described.

3. A draft-hook, comprising an attaching member and a hook member, aneye formed upon the attaching member, a guard-finger formed upon thelowerend of the said attaching member, a reduced portion formed upon thehook member and adapted to extend through a slot formed in the attachingmember,a pivot-bolt for joining the partstr' gether, a head on the saidreduced portion for strengthening the. hook, the lowerend of theguardfinger being so extended to extend outside and overlapthe free endof the hook member, whereby tendency to straighten the book under anexcessive load will be prevented by the pressure. of the guard-fingeragainst the end of the hook, substantially as described.

4. A draft-hook, comprising an attaching memberand a hook member pivotedtogether, a guard finger integral with the attaching member and providedwith a shouldered end portion, a shouldered end portion formed upon thehook mem berforengaging the same, whereby the guard-finger will give thehook lateral support and greatly strengthen the hook, substantially asdescribed.

In testimony whereof I hereunto affix my signature in presence of twowitnesses.
